Global Service Jam is similar to the Global Game
Jam(if you are familiar with that, if you are not is fine, I will explain).
What happens is a bunch of people interested in something come together and
ideate and prototype a project of the thing everyone is interested in. Mostly
in groups that spend 48hours together emerged doing JUST THAT.

Organizing this was already an experience because
thinking about how to call out people to spend a entire weekend on this was
already a challenge. More than that thinking about, ok… we will bring this
people… where? What they need to produce as much as possible and have the right
environment for that? What about the people that might come but might not know
about tools to develop the projects? How to support them? How to build the
right environment?

In the other hand participating was all about the
emersion, I was part of the participation team but because we created a good
environment I got the chance to really participate and get involved. The rush,
the passion of everyone and the willing to create something significant in such
little time… the experience is amazing. Both organizing a experience like this
and participating on it are really inspiring. I totally recommend it. Check it
